Answer 1

Assuming that you have one \\n for the line break and having the same pattern for the body , lets say we have the following

mysql> select * from test \G
*************************** 1. row ***************************
  id: 1
body: Expense = 2000
netIncome = 5000
Gross    = 10000

Now to get each amount we can use substring_index something as

mysql> select 
substring_index(substring_index(body,'=',-3),'\n',1) as expense, 
substring_index(substring_index(body,'=',-2),'\n',1) as netincome, 
substring_index(body,'=',-1) as gross from test;
+---------+-----------+--------+
| expense | netincome | gross  |
+---------+-----------+--------+
|  2000   |  5000     |  10000 |
+---------+-----------+--------+

So for the update it could be as

update your_table
set 
expense = substring_index(substring_index(body,'=',-3),'\n',1),
net = substring_index(substring_index(body,'=',-2),'\n',1),
gross = substring_index(body,'=',-1) ;
